Given the head of a linked list, determine the length of the cycle present in the linked list. If there is no cycle, return 0.

A cycle exists in a linked list if there is some node in the list that can be reached again by continuously following the next pointer.

Constraints:

• The number of nodes in the list is in the range $[0, 10^4]$.

• $-10^5 \leq$ Node.value $\leq 10^5$
